Just ignore any unimplemented Pokémon in there.

In reality any pokemon is fine as long as you have enough to really back yourself up. My competitive teams normally consist of 1 wall, a support, a few sweepers, and maybe 1-2 bulky sweepers to stay in a bit longer.
If this is 1.7.10 version then.. really there isn't much you can use at all.
If this is 1.8 then your list increases by A LOT.
Smogon helps a lot too but use it as only a guide. You can do better than their move sets and EV/Nature recommendations.
